Title:
NANOBUBBLE-GENERATING NOZZLE, AND ORAL IRRIGATOR COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2011/132846
Kind Code:
A2
Abstract:
Disclosed is a nanobubble-generating nozzle capable of generating nanobubbles by allowing gas to flow in flowing liquid without a separate device for mixing bubbles. The nanobubble-generating nozzle comprises: a body of a nozzle comprising a channel for providing a flow pathway to allow liquid to flow through the inside; a nanobubble generation portion forming a part of the channel in which the cross-sectional area reduces and then increases along the flowing pathway of liquid so as to have the pressure lower than the external pressure of the body of a nozzle; and a gas inflow portion provided at the body of a nozzle and connected to the nanobubble generation portion to allow gas to flow in the nanobubble generation portion by the difference between the external pressure of the body of a nozzle and the pressure of the nanobubble generation portion. The nanobubble-generating nozzle can generate nanobubbles by allowing gas to flow in the nanobubble generation portion through the gas inflow portion connected to the nanobubble generation portion by the difference between the external pressure of the body of a nozzle and the pressure of the nanobubble generation portion, and thus can generate nanobubbles by allowing gas to flow in flowing liquid without a separate device for mixing bubbles.
